Appraisal of ground water in the vicinity of the Leadville drainage tunnel, Lake County, Colorado
John T. Turk, O. James Taylor
1979, Open-File Report 79-1538
Ground water in the Leadville mining district occurs in granite, quartzite, limestone, sandstone, porphyry dikes, and unconsolidated material. These rocks form a single aquifer system because the formations are hydraulically connected through contact, mine workings, faulting, and fracturing. The aquifer is recharged by precipitation and water moves toward California Gulch...

Alteration and vein mineralization, Ladwig uranium mine, Jefferson County, Colorado
Alan R. Wallace
1979, Open-File Report 79-1615
Uranium ore at the Ladwig mine, Jefferson County, Colo., occurs in steeply dipping, northwest-striking faults and related fractures with a carbonate-adularia assemblage that forms in altered wallrocks and fills veins. The faults occur between large intrusive pegmatites and garnetiferous gneisses of Precambrian age, and were reactivated as the result of...
Occurrence of uranium in rocks of the intrusive complex at Ekiek Creek, western Alaska
Alan R. Wallace
1979, Open-File Report 79-1653
Uranium in the Ekiek Creek Complex of western Alaska is related to a niobium-rich pyrochlore in the nepheline syenite of the complex. The complex consists of an aegirine-phlogopite pyroxenite that has been intruded and partly replaced by nepheline syenite. The contact zone between the two igneous units varies from a...
Digital-transport model study of Diisopropylmethylphosphonate (DIMP) ground-water contamination at the Rocky Mountain Arsenal, Colorado
James W. Warner
1979, Open-File Report 79-676
Diisopropylmethylphosphonate (DIMP) is an organic compound produced as a byproduct of the manufacture and detoxification of GB nerve gas. Ground-water contamination by DIMP from the disposal of wastes into unlined surface ponds at the Rocky Mountain Arsenal occurred from 1952 to 1956. A digital-transport model was used to determine the...

A proposed ground water quality monitoring network for Idaho
R.L. Whitehead, D. J. Parliman
1979, Open-File Report 79-1477
A ground water quality monitoring network is proposed for Idaho. The network comprises 565 sites, 8 of which will require construction of new wells. Frequencies of sampling at the different sites are assigned at quarterly, semiannual, annual, and 5 years. Selected characteristics of the water will be monitored by both...
Benthic invertebrates, periphyton, and bottom material and their trace-metal concentrations in Salmon Creek basin, Clark County, Washington
Amy C. White, Stuart W. McKenzie
1979, Open-File Report 79-978
In 1978, data were collected for identification and quantification of benthic invertebrates, periphyton, and bottom material and their trace-metals concentrations from three sites in Salmon Creek basin, Wash. Metal analyses included arsenic, cadmium, chromium, copper, lead, zinc, selenium, and mercury. Physical data collected included water temperature, dissolved oxygen, pH, discharge,...
